The study of neospiriferine and spiriferidine brachiopods from the Permian of Timor (Indonesia) present in the collections of the Nationaal Natuurhistorisch Museum (National Museum of Natural History, Leiden, The Netherlands) resulted in a revision of the species Spirifer timorensis Martin, 1881 and Crassispirifer broilii Waterhouse, 2004 and the description of a new species, Latispirifer archboldorum sp. nov. Also, a new genus, Archboldiella, is created, based on the aberrant species Spirifer basleoensis Hayasaka & Hosono, 1951.
